Youtube is full of trading techniques for BTC and alts, many of them seem well researched but I don't know if they actually make good money from it. I read advice that ranges from using just technical analysis to advice that says the best traders only use price action and volume as all technical analysis is just past trends.

In the same way that I would not take bodybuilding advice from someone who was 5'11" and 160 lbs, despite how well researched they are, I would not like to take advice on trading from someone who hasn't actually been able to make it profitable to the point that they can live off their earnings. For that reason, to those who are doing well in trading, what advice and techniques could you give? Hopefully this thread can bring about a good deal of advice that is proven!

Thanks.
